Central composite designs were used for the optimization of ultrasound and microwave processes. The performance of the cell disruption processes in breaking down microalgae cells is dependent on the strain of microalgae. Microwaves (91 °C for 25 min) were the most efficient for the recovery of lipids from <i>N. oceanica</i>, reaching a lipid content of 49.0% dry weight. For <i>N. gaditana</i>, ultrasound process (80% of amplitude for 30 min) was the most efficient in terms of lipid recovery (21.7% dry weight). The two aforementioned processes are ineffective in disturbing <i>T. suecica</i> whatever the operating conditions used. Only the bead milling process at low flow feed rate with 0.4 mm zirconia beads made it possible to extract 12.6% dry weight from <i>T. suecica</i>. The fatty acid profiles of <i>N. oceanica</i> and <i>T. suecica</i> are affected by the cell disruption process applied. The calculation of specific energy consumption has shown that this criterion should not be neglected. The choice of the most suitable cell disruption process can be defined according to numerous parameters such as the microalgae studied, the total lipid extracted, the fatty acids sought, or the energy consumption.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Optimization and comparison of three cell disruption processes on lipid extraction from microalgae","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"microalgae; cell disruption processes; lipids; fatty acid profile; specific energy consumption","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-05-19","DateCreate":"2021-05-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000623182900001","VABBcode":null,"OpenAcc":1,"Handle":"10.3390/pr9020369"},"refs":null,"anarec":{"AnaID":337354,"PubliDate":2021,"Pagination":"369","XtraPublOfAnaID":null,"ISBN":null,"Volume":"9","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":276791,"SerRR":"Processes.
